Replacing the Stone Towers of the Niagara Railway Suspension Bridge with Iron Towers
It is not the intention in this paper to give a minutely detailed description of the old stone towers of the bridge, but merely such a brief description as will explain their condition, the causes which led to their replacement and the manner in which it was done. The stone towers rested on the rock which forms the banks of the gorge spanned by the bridge. On the New York side they were about 90 feet in height, from the rock to the center of the cables, where they rest in the saddles. On the Canadian side, the rock being about 10 feet higher than on the New York side, the towers were about 80 feet high. Each tower, of a pair on either side of the river, had a heavy base of rock faced ashlar, extending to about the level of the upper chords of the stiffening trusses of the bridge, and the two bases were connected by an arch to support the railway track, between the towers, and allow of the passage of pedestrians and vehicles to the lower floor.
